Emergency crews are on the scene at Golden Ears Provincial Park where a boat has capsized on Alouette Lake.
A spokesperson for the B.C. Ambulance Service says not all people on the vessel have been accounted for, but won't say how many people were on-board the vessel to begin with.
Four ambulances and a critical care helicopter were dispatched just after 4 p.m. PT but the helicopter was forced to leave the scene due to windy conditions.
Other first-responders and police continue to search.
